Feature request: show Codex session status in VS Code Sessions sidebar

Summary

The VS Code Sessions sidebar currently lists active Codex sessions, but it does not show per-session status indicators such as Working, Waiting, or similar activity states.

Expected behavior

Active Codex sessions should expose a visible status in the Sessions sidebar, similar to other agent/session experiences, so users can distinguish between:

• working
• waiting
• idle
• completed/error states

Current behavior

Codex sessions appear in the sidebar, but the list omits status details. This makes it harder to understand whether a session is actively running, waiting for input, or idle.

Environment

• VS Code version: current environment
• Codex extension: openai.chatgpt 26.803.61601
• Platform: Linux

Notes

This appears to be a limitation in the current Codex/VS Code integration rather than a workspace-specific setting. A future fix should expose a proper status contract for chat sessions so the Sessions sidebar can render it consistently.

Start by tracing the Codex/VS Code integration path that populates the VS Code Sessions sidebar; no specific file or test is named in the issue. Review how session state is currently exposed, then verify that the sidebar can consistently render working, waiting, idle, completed, and error states.
